Description

CROSS REFERENCE TO RELATED APPLICATIONS OR PRIORITY CLAIM

[0001] This application is a national phase of International Application No. PCT / EP2008 / 051512, entitled “DEVICE FOR CONVERTING THE MECHANICAL ENERGY OF IMPACTS INTO ELECTRIC ENERGY WITH AN OPTIMISED YIELD”, which was filed on Feb. 7, 2008, and which claims priority of French Patent Application No. 07 53151, filed Feb. 8, 2007.TECHNICAL FIELD AND PRIOR ART

[0002] The present invention relates to a device for recovering mechanical energy as electrical energy, in particular to a device able to convert the energy released by impacts of objects impacting on a deformable surface. The objects the energy of which it is wished to recover may for example be raindrops, the device then being disposed in an external environment, or rigid objects, of the powder, grain etc. type in a loading device for example.

[0003] Energy recovery devices are known in the form of a ribbon comprising an element made from piezoelectric material disposed in a fl...
